David I. - "As I understand it, you’d like me to design a mobile native application (for iOS or Android) that helps people manipulate data similar to that of Microsoft Excel or Google Sheets. You can add and import data, edit it, run calculations, regressions, and generate charts and graphs. If it’s ok with you, I’d like to confine the design to iOS, and based on my knowledge of how a product manager uses a spreadsheet. I’d like to approach this problem by first identifying the goal of the app. Since we’r"See full answer

Anonymous Wolf - "Construct a min-heap either inplace, or by making a copy of the array and then applying heapify on that copy. This is done in O(n) time. Maintain two zero-initialised variables - sum and count. Keep popping off the heap while sum < k, and update count. In the worst case you will have to do n pops, and each pop is O(log n), so the algorithm would take O(n log n) in total. Space complexity depends on whether you're allowed to modify inplace or not, so either O(1) or O(n) respectively."See full answer

For example, if I see a drop in user adoption rates, I will evaluate if there are any product experiments that could be negatively affecting adoption. Likewise, was there a technical outage that could have caused a drop? Segmentation and cohorting is also"See full answer
